Objectives: To describe the development of an original scale that measures perceived school climate for active travel in fourth- and fifth-grade girls and boys.Methods: The data were analyzed using confirmatory factor analysis (CFA) to provide evidence
of factorial validity, factorial invariance, and construct validity.Results: The CFA supported the fit of a 3-factor (encouragement, praise, and importance) correlated model for the school climate for active travel measure. This hierarchical model was invariant between sex
and across a 7-month time period, and initial evidence for construct validity was provided.Conclusions: School climate for active travel is a measurable construct, and preliminary evidence suggests relationships with more support for active travel from friends and family.

The American Journal of Health Behavior seeks to improve the quality of life through multidisciplinary health efforts in fostering a better understanding of the multidimensional nature of both individuals and social systems as they relate to health behaviors.

The Journal aims to provide a comprehensive understanding of the impact of personal attributes, personality characteristics, behavior patterns, social structure, and processes on health maintenance, health restoration, and health improvement; to disseminate knowledge of holistic, multidisciplinary approaches to designing and implementing effective health programs; and to showcase health behavior analysis skills that have been proven to affect health improvement and recovery.
